[QUOTE="mna0121, post: 405380, member: 2868"] I am sure it has been noticed that the cam was not degreed. My timing set is not adjustable and I did not want to drill and pin it for a half degree or so. We looked real close to the timing events at TDC, BDC and before on both events and marks were where they should have been so I am going to trust the cam company on this one. If this were a boosted engine certainly it would have an adjustable double roller set up and I would have dialed it in. Moving the build from JR's shop to one of our barns for the finish. We wanted to get the intake on and a couple of items addressed before leaving JR's but the intake does not line up with the heads. These Trick Flows were 69 cc's from the factory but have been cut to 59 cc's. When heads get cut it moves the center line down towards the pistons and changes the mounting angle because of the wedge shape of an engine. You can get away with a little cutting and still get a good seal but at some point the intake has to be cut to get it back in line. I have ran into this before, even having to use spacers on a tunnel ram I bought that had been cut so much it fell between the heads. Guess I will call FAST next week and ask about the gasket recesses and how to go about machining the surfaces. [/QUOTE]
